摘要

We recently identified the marginal zone B and B1 cell-specific protein (MZB1) as part of a gene expression signature associated with outcomes in chronic lymphocytic leukemia (CLL). MZB1 is important for B cell function as a key regulator of antibody secretion, calcium homeostasis and adhesion. Therefore, we analyzed the role of MZB1 expression levels in 139 patients with CLL using quantitative real-time polymerase chain reaction (qRT-PCR) and microarray data sets in CLL, follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), multiple myeloma (MM) and acute myeloid leukemia (AML). High MZB1 expression was associated with inferior survival in CLL (hazard ratio [HR]: 1.63 [confidence interval (CI): 1.14-2.33], p = 0.007), FL (221286-s-at HR: 1.16 [CI: 0.98-1.37], p = 0.086; 223565-at: HR: 1.3 [CI: 1.1-1.61], p = 0.015) and DLBCL (221286-s-at: HR: 1.17 [CI: 1.06-1.3], p = 0.003; 223565-at: HR: 1.21 [CI: 1.08-1.35], p = 0.001). In DLBCL MZB1 expression was an additive prognostic marker in a multivariate model including activated B-cell like (ABC) versus germinal center (GCB) subtype. Additionally, MZB1 expression correlated with a unique gene expression pattern. This study is the first to show that the expression level of a single gene has prognostic significance in different lymphoma subtypes. Due to its biological function, MZB1 may play a central role in B cell neoplasms and is a potential target for future therapeutic interventions.
